PLOWL specification of Letters ,Fatema To all 'whom 'it may concern:

Be it known that I, CYRIL B. CLARK, a citizen of the United States, residing at New Albany, in the county 'of F loyd and State' of Indiana, 'have invented certain new and useful Im rovements'i' Plows; and I do here-' by dec are the followi to be a full, clear, and exact description %the invention, such as will enable others skilled in the art to which itappert-ains to make and use the same.

This invention relates to improvements in plows and particularly to Wheel plows.

The invention comprises the provision of a. Wheel plow having a frame and Wheels for supporting the same, and a plow designed to be reversed without reversing the frame.

The invention-further comprises the provision of a Wheel plow arranged with means for reversing the plow Without reversing the frame, and'means for Varying the cut of the plow.

The invention still further comprises the provision of a Wheel plow having a frame and supporting Wheels arranged to support the plow and opera-ting mechanism therefor, various means for raising and lowering the plow, means for reversing the plow, and means for varying the angle of draft upon the plow.

The Object in view is the provision of a plow which may be reversed Without re-- versing the frame carrying the same, and the provision of a plow that may have the cut adjus'ted for varying widths.

Another obj ect in view is the provision of improved raising and lowering means for a Wheel plow, means for rigidly holding the plow at a 'proper angle and yet have free easy rotation'ther'eofland means for regulating the angle of the carrying or supporting Wheels in relation to the angle of the plow.

With these and other objects in view the invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter more fully described and c'laimed. V

In the accompa-nying' drawin s: Figure 1 is a perspective *View of one em odiment of the present invention. F ig. 2 is a *side elevation of the structure shown in 'Fig. 1, the same being taken from the opposite side to that of '1. Fig. 3 is .a top plan view of the 'structure shown-in Fig. 1.

Fig. 13 is a fragmentary sectional view on line 13-13 of Fig. 12. Fig. 14 is an enlarged detail' fragmentary sectional -view approximately on line 14-14 of Fig. 3.

in constructing a 'low according to the present invention a amework is provided havin a supporting bar 1 designed to have its ends supported by supporting wheels 2 a'nd 3 and a second bar, 4, substantia ll semicircu'lar sustained by su porting w eel 5. By this construction a i i-amework is provided that is sup orted and evenly balanced upon three whee s one of which is designed to travel upon the unp'lowed ground during operation and two of which are designed to travel in the furrow.

The beam *or a art 'of frame '1 is bent u on the are of a circ e at 6. This bend is re erably positionedopposite thesemi-crcilar member 4 and has secured thereto a bracket 7 that is designed to receive a shaft or journa'l 8. The sha'ft or journal 8 is the shaft that through proper Connecting means receives the plow as 'disk 9 and determines the osition of the same. The bracket 7 is ormed with the ears 10 and 11` which are slotted at 12 and 13 through'which bolts 14 and 15 pass. The bolts 14 and 15 are designed to pass entirely "through the curved part of member 1 and through a plate or bracket 16, as clearly seen in Fig. 13. The

bracket 7 and lugs or extensions 10 and 11 are formed with flanges which extend or* Petented Jan; 12, 1909.

this structure a comparatively large bearing or grippin surface s provided and a strucnumber of ape r which bolts' 14 and 15 may passfor ture s prouced that will prevent any tendency to twist or turn. The curved portion 6 of bar 1 may be provided -with any desired rtures 14' and 15' throu 'h P P y positioning the shaft 8 substantially central of the are .shaped portion 6. The main ad-' justment, however, of bracket 7 and consequently shaft 8 is b means of the slots 12 and 13 which norma ly form a suflicient adjustment of bracket 7 'to correctly osition shaft 8 so that the' plow 9`will make t e same cut in either position. Ordinarily the slots 12 and 13 are sullicient for the proper adjustment of bracket 7 so that bar 1 will be only provided with one set of holes or apertures.

Positioned in bracket 7 is a journal 8 that has a bearing member 17 formed at an angle to the main shaft. The bearin member 17 is formed with a flaring end 18 or receiving or having placed thereover retaining members 19.` The retaining' members -.19 are preferably formed in a plurality of parts and are secured in place by bolts as 21 to disk securing member 22. The disk or plow receiving member 22 is formed in the shape of a disk and has one side concave for `permitting the disk plow 9 to snugly fit therein and be secured thereto by bolts 22' and has the other side formed With an extension 23. The extension 23 is designed to be machined off until perfectly smooth for a bearing member 23 designed to rotate in a cu bearing 24 that is also preferably mac 'ned for forming a more rfect bearing surface. The cup shaped aring member 24 is designed to fit in bearing member 17 and project a short distance therethrough, as clearly seen in" Fig. 7, ;suitable sr fth be or reventm any ppn o e arng mem r. O-inarily* in opration the pres` sure against plow 9 will cause all of the frietion to be exerted upon bearing members 23 and 24 and retaining members 19 act simply as means for preventing accidental displacement of the plow.

The shaft 8 is formed at its upperend forming 'with a beveled squared portion 26 and a' rethrough a ental gear 29 and to receive power there m for turning shaft 8 and connected parts. Gear 29 has formed oppositetheteeththereofalugorextesionio 20 and cy or spline 25 being provided' a a corrugated that is ,reduced at 31. for formin -shoulders 32. The reduced portion 31 is esigned to j pass upward through an arm 33 that carries a scraper 34 which s used for cleaning low' 9. Arm 33 is formed With an enlarge lug 35 that has provided therein an elongated slot 36 through which the reduced portion31 extends. By means of lug 35 and shou'lders 32, arm 33 s held' in a sufliciently elevated x position to permit 'plowc to pass thereunder, as seen in Fig. 2. The arm 33 carriesat its outer end a bracket 37 which is adjust- 'ably secured to arm 33 by means of bolt '38, a

slot 39 being formed inarm 33 for ermit-v ting the adjustment of bolt 38. Bracket 37 carres a shaft 40 that is held in position' by a cotter-pin 41. This shaft is desi ed to carry a scraper 34 and to permit a ee rotation of the same, the cotter-pin 41 limiting the downward movement and the arm 33 limiting the upward movement. By this construction the scraper 34 is adjusted automatically to any angle or contingency r arisng n re ard to the disposition of disk 9 and by its ree rotation permit the disk 9 to be 'moved to cut in either direction. The arm 33 is pivotally mou'nted at one end upon shaft 42 that passes through and 'acts as a journal for segmental gear 43. Shaft 42 s also secured n an extension on' bracket 44 formed integral with .plate 16. By this construction t will be observed that arm 33 simply movesupon the are of a circle with shaft 42 es a center and the movement of the arm is regulated by the movement of the standard 8. For adjusting manually the position of scraper ,34 bolt 38 passing through the outer end *of arm 33 is moved together V with surrounding parts. By this arrangev ment the scraper may be caused to impinge.

against the disk 9 with greater or less fore' and also the scraper 34 may be adjustedv for:

difi'erent size disks or plows. The arm 28 is designed to .though acting as a washer for accomplishing the purpose has as its main Object to provide means for automatically turmng the wheels 2 and 3 when the disk 9 is reversed.

Arm 28 is bent upward at 46 and back again.

have V portion 27 of standard 8 passed therethrough at 47 to any desired distance, preferably to member 27. The bent over portion 47 is formed with a slot 'or elongated aperture through which passcs a bolt 49. The turned over portion or member '47 is preferably'cormgated upon its upper sui-face for receiving 50 which also pernits bolt 49 to pas therethrough. Enc-clng shaftorbolt49is washer or clamping member,

iso

clamp or bearing 51 provided With ears 52 and 53. Surrounding bolt 49 and positioned Within member 51 is a bearing sleeve 54. To the bearing or clamping member 51 are pivotally secured arns or links 55 and 56 which extend to the ends of the frame and are connected by means hereinafter more fully described with wheels 2 and 3 so that when arn 28 is moved by reason of gear 29 being moved and surrounding mechanisn wheels 2 and 3 will also be moved in proper relation thereto. The clamping of nut 45 against arm 28 ordinarily Would be sutlicient to cause the rotation of arm 28 with shaft 8. but to make the action positive arm 28 is cut away at`57 for permitting a partial encircling of member 30 which is formed integral With gear 29.

Wheel 2 is preferably formed as seen in Fig. 5 with a V shaped rim 58 for engaging the earth for preventing any lateral'or skidding movenent of the plow. A shaft 59 is designed to pass through wleel 2 and has Wheel 2 secured thereto by neans of a bracket 60 clamped to the bent portion 61 thereof and a washer or stop 62. The washer or stop 62 is provided with a pin 63 which preferably passes through shaft 59 and fits into apertures or slots 64-64 in washer 62. The hub of Wheel 2 has formed thereon lugs 65-65 which are designed to receive bolts 66-66. Bolts 66-66 are designed to pass through lugs 67-67 in a clamping or retaining member 68. By clamping member 68 to the hub of Wheel 2 the Wheel camot oscillate to any considerable degree as washer 62 will prevent any outward movement of the Wheel and member 68 will prevent any substantial inward movement thereof. In addition to member 68 preventing lateral movement of Wheel 2 clamp 60 also will prevent any inward movement of the 'Wheel 2. Shaft 59 after passing through wheel 2 is bent at 61 and extends upward at an angle to the plane of Wheel 2, as seen in Fig. 4, and is designed to receive sleeve 70 of bracket 69. Sleeve 70 is designed to reciprocate upon the upright shaft. 71 of axle 59 and is moved thereon by the action of lever 72 acting through link 73 and segmental rack 74. Segmental rack 74 is secured to ears 75-75 for-med on sleeve 70 by means of bolts 76-76. Segmental rack 74: has an extension 77 to which lever 72 is pirotally mounted at 78 as clearly seen in Figs. 1, 2 and 8. Link 73 is pivotally secured to lever 72 at 79 and pivotally mounted at 80 to a bracket 81, the connection for lever 73 at 80 being loose enough for permitting the desired rotation of member 71 whr-never actuated by the parts 8 1 and 84. By this construction a fulcrm is formed and leverage given to lever 72 for moving upward and downward bracket 69. Bracliet 81 is held in position upon a squa'ed portion 83 of shafi: 71 so that whenever bracket 81 is moved shaft 71 will be rotated for keeping the position -of Wheel 2 in the same general -relation to bracket 81. Bracket 81 is bent downward at 8-1 any desired distance and has passing therethrough a stud 85 that is formed with an enlargcd portion 86 through which a bolt 87 is passed for Connecting arm 55 with enlarged portion 86.

Bracket 69 is formed with flanges 88 and 89 for partially encircling the end of beam 1, as seen in higs. el and 6. At. the end of beam 1 which is engaged by bracket 69 a. plurality of apertures 90 are formed through which a suitable securing means as bolt 91 is passed. A suitable aperture or hole 92 is ormed in bracket 69 for accommodating bolt 91. The ape'tures 90 are designed to permit a lateral adjustment of bracket 69 so as to vary the cut of plow 9.

Wheel 3 is provided with a lever 93 similar to lever 72 and also with connected mechanisn Similar to the mechanism set forth in connection with Wheel 2 and therefore will need no extended description. The Wheel 3 and lever 93 and surrounding meclanism are positioned at the opposite end of the frame of the plow to Wheel 2 and surrounding mechansm and are designed to be operated in a sinilar nanner for raising and lowering a bracket Similar to bracket 69, and also that end of the frame. By this construction the ends of the' frame uay be raised and lowercd for raising and lowering disk 9 for varying the depth of the cut or entirely removing the plow from the ground.

Rigidly secured to gear 43 is a tongue 94: that extends from gear 43 over the frame 4 and is designed to rest thereon. `ormed on a clamping member 94' are lugs 95-95 to which is pvotally secured a locking member 96. The looking member 96 is designed to rest normally within notches 97 and 98 respectively according to the direction the plow is traveling. The looking bar 96 extends above tongue 9 1 a short distance and has secured thereto a foot lever 99-which is preferably formed heavy at one end as 100 for normally acting upon look 96 to force the same into engagement with aperturcs 97 and 98. Vhen it is desired to move looking member 96 out of ei agenent With either of the notches 97 and 98 the lever member 99 is preed at point 101 which cause the looking member to move or turn upon its securingmeans in ears 95-95. After looking member 96 has been ths the tongue 94 nay be moved around over Wheel 5 until locking member 96 comes op-` posite the other notch. When the looking bar 96 comes opposite either of the notches 97 or 98 the same Will move into the notch by reason of the Weighted end 100 of member99no-mallyforeingthesameinthat direction. A bracket or ,retainin member 102 is' secured to tongue 94 n order to prevent the tongue from leaving frame 4 and thus causing locking member 96 to become 5 disegaged accidentally, The use of the guiding or retainin member 102 also prevents any raising o the tongue 94 and consequent twisting of the shaft42 and sur- A rounding parts, and in addition acts as a lug or brace secured to tongue 94 for communicating owerexerted on tongue 94 to the frame of the plow for assisting bracket 16 to communicate power to the frame from tongue 94. l

Secured to the outer end of tongue 94 is xe/a hitching member or clevis 103 which is rigidly secured to a lever 104 by any suitable means as bolt 105. Lever 104 is pivotally mounted at 106 to tongue 94 so that 20 when' power is applied to member 103 the same will be communicated to the tongue and from thence to the remaining part'of the plow. A segmental rack 107 is secured to the tongue 94, which is designed to receive a bolt 108 secured to lever 104. The bolt 108 is provided with a spring and au operating band lever 109 in the usual manner for causing the same to engage the tceth of rack 107 and to be disengaged therefrom 0 by the operator at will. By this arrangement thedraft on the plow may be vared quickly and without any unbolting or adjusting of parts but by simply moving lever 104 to any desired position on rack 107.

Frame 4 is bolted to frame 1, as clearly seen in Fig. 3. by bolts 110 and 111. The

'frame 4 is designed to extend over at 112 and 113 for forming in a certain sense g'ipping' members together with bolts 110 and 40 111 for firmly holding frame 4 in position.

For-med at a point on frame 4 mid-way between bolts 1.10 and 111 is a depending lug 114. The depending portion 114 is designed to form a supporting member for shaft 115 5 -which is bent for forming an axle 116 which inturn carries wheel 5.' The hub of wheel 5 has formed the'eon a flange 117 which is encircled by a clamping member 118. The clamping member 118 is formed in two parts and bolted together around axle 116 and also flange 117. Immediately above lug 114 is formed a cut-away portion 119 that \is designed to give axle 1'16 a space for swinging and permitting wheel 5 to travel in line pa rallel with the direction of movement of the plow. v

' Inuse power is applied to clevis 103 and from thence through tongue 94 to the frame' composed of members 1 and 4 and from thence to the remaining parts of the plow. As the plow progresses the disk 9 or plow proper passes through the earth and revolves as the same progresses. After the plow has reached the end of the field and it s desired to make a return trip the member 99 is pressed at point 101 and lockin'g member or bar 96 is moved out of notch 97. Locking bar 96 is held disengaged from notch 97 until ton e 94 has been. moved slightly upon its pivot 42 toward-wheel 5. Tongue 94 is continued in its movementruntil looking bar 96 falls or moves into engagement with notch 98. During the turning of the tongue segmental gears 43- and 29 mesh and as-gear 43 rotates .gear 29, and 76 shaft S` will be rotated, as the same is rigidly connected to gear 29, plow 9 being mounted in a bearing carried by shaft 8 also rotates and takes a proper position corresponding to tongue 94 for cutting a return 80 furrow. During the turning of 'gear 29 links. 55 and 56 are moved or reciprocated which in turn will move brackets 81. The movement of brackets 81 will be communia cated to wheels 2 and 3 as heretofore set 86 forth for varying the angle of the same. In changing the width of the cut the angle of the wheels 2 and 3 must be altered. This is acconplished by varying the position of shaft or bolt 49 in the bent over portion 47 90 of arm 28. A manual adjustment is also provided by means of apertures 120 Fig; 1 provided in the ends of rods 55 and 56 for varying the position of these rods in relation to brackets 81. By the construction of arm 28 and surrounding parts together with links 55 and 56 brackets 81 and connected parts means are provided for automatically turning wheels 2 and 3 at the same time plow 9 is turned .and to a proper position. By this means and the means for automatically reversing the plow 9 it is not neces- "sary to turn the frame of the plow or to even move the plow from the ground but to simply turn the same to a reversed position and to pass over the field for a return trip. \Vhen it is desired to raise the plow out of the ground entirely or partially as may be desired levers 72 and 93 are operated for raising brackets 69. This will raise member \1 and consequently plow 9 to any desiredposition.

'What I claim is:

1. In a plow, a frame, wheels for supporting saidframe, a plow standard, a 'bracket secured to said frame for supporting said standard, said bracket being formed with elongated apertures for permitting adjustment thereof for varying the position of said plow standard, a reversible beam, and means Connecting said reversible beam and said plow standard whereby when said beam is reversed said standard will be reversed.
